What is causing this?
1993 FLSTC Heritage Classic.
First press on the start button, I get a delay and a whine. Second press on the button and it starts right up every time. It does it hot or cold.
What I've done so far that hasn't fixed it:
New battery
New starter
New relay
New cables
Checked cable resistance
New start button
New stator
New regulator
New ignition
Cleaned battery connections hot and ground
Cleaned ground connection to frame
Separated plug connections and cleaned contacts
Could it be a timing related issue?
What else can I look at? I tell ya, fugg these Evos

It's happened, be honest it sounds like a connection issue somewhere, start checking the small grounds like for the starter relay or the handle bar control's

I would assume a new starter came with a new solenoid.
If it did, you got a bad one with the new starter.
The starter clutch is a sprag clutch. It locks up driving the motor. It only slips if motor starts and out runs electric motor which lets the rollers run back dow the ramps.
It doesn't slip. It's possible if the grease is dry and caked and rollers have the springs held down is slip position, it could slip but highly unlikely.
That hesitation is poor contact on the solenoid that applies the heavy amperage required by starter motor.

Can you describe more of the whine sound? Electrical or mechanical sound? Location?
Have your run larger gauge ground wire from the starter relay connector?

I was thinking something to do with the starter or solenoid, but after checking everything that you do maybe time to trade it in on a new one.
